电网规模的扩大,已面临着输电线路走廊资源以及基础设施造价高的问题。近年来提出的交直流线路同塔多回架设的输电方式,成为了一种节约资源的选择。然而这种同塔混合多回输电线路的耐雷特性尚需进一步研究以确保输电安全。基于电磁暂态仿真软件ATP-EMTP,搭建了±800 kV/500 kV交直流同塔多回输电线路的仿真模型,分析在不同接地电阻以及杆塔高度情况下的反击耐雷水平,与单独架设的±800 kV直流线路以及500 kV交流线路进行对比;采用改进EGM和EMTP相结合,计算了交直流同塔多回输电线路的绕击跳闸率,根据仿真计算结果,提出了提高交直流同塔多回输电线路的耐雷水平的措施;降低接地电阻或者降低杆塔高...

With the development of grid, the problem of high transmission corridor resources and high infrastructure costs is already under way. So in some areas, in recent years, it has been put forward that the AC and DC lines with the same tower will be a kind of resource saving option. However, for the same tower lightning withstand performance of hybrid multi circuit transmission line, further study is needed to ensure the safety of transmission. Based on the ATP-EMTP a simulation model of overhead transmission line with ±800KV/500 AC and DC transmi...
